Antioxidant activity of various plant part extracts of G. superba (L) and U. indica(Roxb) Kunth

摘要

ABSTRACT Antioxidant potential of different plant parts of G. superba and U. indica was determined by using DPPH (2,2-diphenyl-2-picrylhydrazyl hydrate) assay and ascorbic acid as standard compound (IC50: 10 g/ml). The maximum antioxidant potential in G. superba was found in leaf (IC50: 28g/ml) followed by rhizome (IC50: 95g/ml) and Stem (IC50: 120 g/ml). In U. indica bulb (IC50: 113 g/ml) showed maximum antioxidant activity than the leaves (IC50: 520g/ml). Keywords: Antioxidant, G. superba, U..
